◇

Alpine Provenance

Every mineral we work with is sourced from specific alpine deposits between 1,400 and 2,800 meters. The crystalline structures formed at altitude under extreme pressure produce optical properties unavailable in commercially mined gemstones.

◆

Geometric Purity

We never fight the crystal's natural geometry. Each setting is designed around what the mineral reveals under magnification — the facets follow the stone's internal lattice, not a predetermined template. No two pieces can ever be identical.

◈

Lifetime Provenance

Every Crestille piece ships with a geological certificate detailing the mineral's exact origin, formation depth, and spectroscopic analysis. The story of the crystal is as important as the setting that holds it.

Crestille Atelier
The Workshop

Where Crystal
Becomes Jewelry

The Crestille atelier occupies a converted 19th-century mineral assay building in Chamonix at 1,800 meters. The stone walls and mountain light create conditions that allow the jeweler to see exactly what the collector will — the play of natural alpine light on the mineral surface.

All setting work is done under 10x magnification. Prong geometry is calculated against the crystal's natural cleavage planes to ensure the stone is never under structural stress.

From Crystal
to Collector

I

Mineral Prospecting

We prospect specific alpine veins each season, working with geological maps that have been refined over two decades. Raw crystals are selected for optical clarity, formation geometry, and structural integrity — discarding over 80% of what we find.

II

Spectroscopic Analysis

Each selected mineral is subjected to full spectroscopic and refractive index analysis. This data forms the basis of the provenance certificate and informs the setting design — particularly regarding which faces of the crystal should be exposed for maximum optical effect.

III

Setting Design

The setting geometry is drawn specifically for the individual stone — we do not use templates. Precious metal choice (18k white gold, rose gold, or platinum) is determined by the mineral's color frequency to maximize visual contrast.

IV

Hand Setting

Setting takes 20–60 hours per piece under 10x magnification. Prong positions are calculated to align with the crystal's cleavage planes, distributing stress evenly and allowing maximum light transmission through the stone's natural geometry.

V

Documentation & Delivery

Every piece ships with a complete geological and craft certificate: mineral origin coordinates, formation depth, spectroscopic data, setting metal specifications, and the maker's signature. The certificate is as irreplaceable as the piece itself.

Legacy

Two Decades
in the Mountain

2003

First Piece

The first Crestille piece — a Mont Blanc aquamarine set in 18k white gold — sells to a private collector within 48 hours of completion.

2010

Spectroscopic Archive

Completion of the first comprehensive spectroscopic archive of Chamonix-area mineral deposits, referenced by subsequent geological research.

2017

Salon de Bijoux Award

Receives the Salon de Bijoux d'Exception award for mineralogical jewelry, the first alpine atelier to win in the award's history.

2024

Permanent Collection

Three Crestille pieces enter the permanent collection of the Musée National des Arts Décoratifs, Paris — recognition as significant objects of craft.

Recognition

Critical Attention

"Crestille operates at the intersection of geology and jewelry design — a discipline that has no established framework, which is why their work feels genuinely new. The Mont Blanc aquamarine is one of the most beautiful objects I have ever held."

— Vogue Paris, December 2023

"The geological certificates that accompany each Crestille piece elevate the transaction from commerce to scholarship. You are not buying jewelry — you are adopting a piece of the Alpine geological record."

— Financial Times How to Spend It, 2024

"There is a stillness to Crestille jewelry that is difficult to articulate. It comes from starting with the mineral's own geometry rather than imposing a human template. The result is jewelry that looks inevitable rather than designed."

Commission

Begin Your
Piece

A Crystal Found for You

A commission begins with a mineral. We discuss which stone family interests you — aquamarine, tourmaline, quartz, obsidian — and what optical character you are drawn to. Then we prospect specifically for your piece.

The process takes between 4 and 12 months from commission confirmation to delivery. We photograph every stage and send updates as the piece develops.

◈Commission pieces from €8,000
